title: In silico method to predict functional similarity between two RecA orthologs.
abstract: RecA is a highly conserved bacterial protein that plays crucial roles in many cellular processes and hence is a potential target in the chemotherapy of bacterial infections. An understanding of the functional similarity between RecA proteins from different bacterial species should yield further insights into the biochemistry of RecA protein, along with the potential for new approaches to facilitate the improvement of RecA-targeted drugs. In this technical note, the authors present an in silico method based on tri-oligonucleotide usage correlations (TOUC) to predict the functional similarity between two RecA orthologs. The TOUC values analyzed in this study are in good agreement with the available experimental results. This method should prove useful in guiding future experimental efforts aimed at furthering our understanding of the biochemistry of RecA proteins and subsequent development of new drugs that modulate RecA biological activities in bacteria.
